Alaska Air also does quite well on getting your bags to the carousel in a timely manner.
(All the usual disclaimers that I've no connection to the airline, except as a satisfied customer...yada....yada.)
I flew Alaska only once, and I had a great experience. They handled the second leg of a work trip I took, and a different airline handled the first leg. Well, first leg airline misplaced my checked luggage, and I needed to do a presentation for work. Alaska took responsibility -- yes, they took responsibility for another company's goof up -- and bought me the whole professional getup -- suit + shirt + belt + shoes. I'll definitely fly Alaska again.
